All About Photo Etching:
The contemporary era is now entering into future technological time, which was never so promising, and offering the most acceptable excerpts derived using the latest technological innovations. People living in this era are just enthralled with the terrific inventions. Photo etching is the latest technological outcome making life more comfortable and exciting.
To meet the growing consumer boom for a more innovative and sophisticated lifestyle, it encourages the manufacturers to introduce more of such technological fantasies. These types of innovations require diligent and expert craftsmanship to design and equip with meticulous precision. The manufactured products should be value-added cost-effective.
One of the lesser-known technics in this fast-paced and widely accepted utility is Photo Etching. This process needs some delicate and thin metal parts having the required design on them—this reducing photo fabrication progression, also known as chemical etching. Photochemical etching is a multi-step operation using photo-sensitive developing material to transfer part images onto metal sheets before a chemical etchant dissolves the unwanted sections, leaving the desired dimensions only.
What is the Photo Etching Process?
Photo etching is a precision manufacturing process involving thin metal parts and the designs to be mounted on them. The process is a multi-step operation using photo-sensitive material to transfer the designs or images on the metal surface. It is generally done using chemicals in the manufacturing industries. The chemical etchant liquefies the unwanted segments, leaving only the desired part proportions, and it does not affect the metal properties.
The etching process may refer to a printmaking technique to prepare artistic designs, a decorating technique on the glass and metal surface, etc. The meaning of an etcher is related to a printmaker. Other known terms used for photo etching are metal etching, photochemical etching, photochemical machining, etc.
How does it function?
On receiving the part dimensions, it would be decided by the manufacturer how many pieces will fit on the metal sheet of the pre-determined sizes. More the pieces per sheet, the cost will be lower.
While deciding the sheet’s size, the metal and tolerances’ thickness are the vivacious factors to be considered. On the other hand, thinner metal will increase the part pieces. The important thing here is the metal does not change its properties.
The following process takes place is laminating. The chemical etching metal process laminates each sheet of metal with a photoresist film. The film is applied on both sides of the metal sheet. The process takes place under yellow light since this photoresist film is sensitive to UV light.
Photochemical etching is used extensively to manufacture customized meshes, filters, and other filtration accessories; unlike orthodox machining technologies, the process offers countless variations. Meshes can be etched using any metal, including those considered hard to machine or highly ‘non-corrosive.
The Benefits of Photo Etching:
The benefits of photo etching for thin metal parts are precision edges with low tolerances. The chemical metal etching process leaves a smooth, even surface free from roughness and burrs, depths, and pressure adjustments. Other attractive features of the etching process are speed and low-cost for parts involving features and intricate designs.
